Analysis of Meaning
The Doctrine of the Mean once wrote: "? A gentleman is cautious and independent, and does not cheat the darkroom. Humble and self-grazing, including Zhang Kezhen? 。” It means that when a gentleman is alone, even if others can't see or hear, he should be cautious and not do anything that violates moral laws. But there are always people in this world who indulge in greed and desire, and instead of being a real gentleman, they become real villains.
As the ancients said, "A tiny mistake is a thousand miles away." Therefore, a modest gentleman can only go far if he is cautious and cautious and tightens the string of law. "Being cautious and independent" is the wisdom crystallization of the ancient people's self-cultivation and governing the country. Learning is a process. The key is to learn lessons and be strict in self-discipline, so as to truly "endure hardships, resist temptations and manage details".
